Nice:


YouTube - Engine Explosion dyno room

[Laneco]

Ewww.... That was expensive. Bet it was really, really LOUD too!

Wow, they should have used that BG System of engine lubes that guarantees against engine failure.

LOL! Good one...

Motor Meister?

runaway diesel?

[azasadny]

Ouch!

[ODDJOB UNO]

welcome to "ON-STAR", would you like a systems analysis update?

[Rusty Heap]

after watching that many many times back to back, you can see a vertical linear bearing or pneumatic cylinder in the back ground that controls a water flow valve, engine isn't under any load till half way through the dyno run.

Most likely, this is a hydrostatic dyno where you put more and more load on it via the engine turning a water pump and you can vary the load this way (did some dyno work back in College with a beater 2 barrel carb'd Chevy 350 on a waterdyno) it took 8-10 horsepower just to idle the engine, keeping the piston mass/crank/oil pump/valve train resistance all spinning.

Note 1/2 way through the video, the vertical actuator in back drops, openning the water valve, engine reacts by torque rotation to the left, raising up on the right, and then the birthing process starts.


Yeah that was an ucking fugly way to kill an engine, and a big mess to clean up too with all the oil pouring out of the front of the pan at the end.

[asphaltgambler]

For even "more better engine failures" - google -search or you tube pro stock or super stock diesel pulling tractors where they run as much as 100psi of boost or more and spin the engines three to four times the OE rev limit.

Man when those things blow - they REALLY blow

Interesting observations!
I worked at a GM lab that had 6 engine cells. Had to clean up after a number of failures. The worst was a 6.2 diesel driving a 700R4 that blew so spectacularly that initially we couldn't tell whether the engine or the trans had failed first. We used eddy current dynos with an inertia wheel so if something went bang it kept turning for a while and did lots of damage. Had some good times and interesting experiences in that lab.

This poor thing was put out of it's misery.

Thanks for explaining that. You hear it start working at :24 with that whine...I wondered why it did that.

Excellent.... I liked how the guts fell out the bottom.

Almost looked liked a gutted animal
